Osmosis is the process through which water moves across a semi-permeable membrane from an area of lower salt concentration to an area of higher salt concentration. This process is reversed by the reverse osmosis system in order to remove salts and other particles from water by utilizing pressure to force water across a semi-permeable membrane. Reverse osmosis systems are now utilized in the homes for purification of the drinking water.
